Latest Gamma-ray bursts Stories
For the first time ever, scientists using the Atacama Large Millimeter/submillimeter Array have discovered molecular gas in galaxies that had once been rocked by gamma ray bursts, according to new research published Wednesday in the journal Nature.
Scientists had originally believed all gamma-ray bursts were followed by a radio afterglow, so Australian astronomers of the Centre for All-sky Astrophysics at Curtin University and the University of Sydney decided to set out to prove this theory.
On Saturday, April 27, the Fermi Gamma-ray Telescope detected a sudden, powerful flux of high-energy gamma-rays, indicating a historic burst event in a distant galaxy. The instrument then notified other telescopes located in space and on the ground that a Gamma-ray Burst (GRB) had been detected.
ESAâ€™s Integral gamma-ray observatory has provided results that will dramatically affect the search for physics beyond Einstein.
WASHINGTON, April 7, 2011 /PRNewswire-USNewswire/ -- A new supercomputer simulation shows the collision of two neutron stars can naturally produce the magnetic structures thought to power the high-speed particle jets associated with short gamma-ray bursts (GRBs).
An enormous eruption has found its way to Earth after traveling for many thousands of years across space.
Integral has captured one of the brightest gamma-ray bursts ever seen. A meticulous analysis of the data has allowed astronomers to investigate the initial phases of this giant stellar explosion, which led to the ejection of matter at velocities close to the speed of light.
UK astronomers, using a telescope aboard the NASA Swift Satellite, have captured information from the early stages of a gamma ray burst - the most violent and luminous explosions occurring in the Universe since the Big Bang.
Using the powerful one-two combo of NASAâ€™s Swift satellite and the Gemini Observatory, astronomers from a number of institutions, including Johns Hopkins, have detected a mysterious type of cosmic explosion farther back in time than ever before.

Gamma-Ray Burst -- In astronomy, Gamma-ray bursters (GRBs) are flashes of gamma rays that last from seconds to hours, the longer ones being followed by several days of X-ray afterglow. They occur at random positions in the sky several times each day. They are now believed to result from tremendous explosions in far away galaxies, during the creation of a black hole from a dying star or two colliding neutron stars. The black hole, surrounded by a rotating disk of matter falling into it,...
